Effects of using a low slippage percentage
When performing a Swap or CrossPay in Zodl, you'll see a slippage tolerance setting with a default value of 2%. This setting defines the maximum price movement you're willing to accept between the time your swap is quoted and when it fulfills.
Lowering this value may seem like a way to get a better price, but it can have the opposite effect: your swap may take significantly longer, or it may fail to complete altogether and be refunded.

Why slippage matters
Slippage acts as a ceiling, not a target. You'll still receive the best available price on NEAR Intents at the time of fulfillment – the percentage simply sets the maximum deviation allowed before the swap is rejected to protect you from overpaying.
If market depth isn't sufficient to meet a very tight slippage (for example, 0.25%), one of two things will happen:
- The swap will wait for better market conditions, taking longer to complete
- The swap will fail and be refunded to your provided refund address
Our recommendation
We recommend keeping slippage at the default of at least 2% to ensure the greatest chance of completion. This is especially important for:
- Larger swap amounts, where market depth is more likely to be a factor
- Less liquid tokens, where tight slippage is harder to meet
- Volatile market conditions
You're not sacrificing anything by leaving slippage at 2% – you'll still get the best available price, and your swap is far more likely to complete in a timely manner.
